He Was...A French chemistReferred to as "Father of Modern Chemistry"Married to a young, beautiful 13 year old girlAn author of many books such as "Considerations Generates sur la Nature des Acides"What about John Dalton?He proposed that all matter is composed of tiny particles in 1806He is known for developing the concept of atoms into a scientific theory that has become the foundation of chemistryHe developed his Atomic Theory with the help from The Law of Conservation of MassHe was able to put together atoms that are indestructible, they can rearrange but do not break apart.Their Importance TodayDalton's Atomic Theory, the Law of Conservation of Mass, and the Law of Definite Proportions are basic laws that have created a foundation for the study of chemistryWithout the findings of Lavoisier's, there would have been more difficulty for Dalton' theory and Proust's Law to be discoveredLaw of Conservation of MassStates mass is neither created nor destroyed during chemical reactions, but that it is conservedThe mass of reactants is equal to the mass of the productsHe discovered this in the year of 1785Who was Joseph Proust?He was a chemist who conducted several tests on chemical substancesHe discovered that each pure compound has its own characteristic element compositionHis discoveries led to the Law of Definite Proportions, which says that the proportion by the masses of two given elements will always remain the sameFactsBorn on August 26, 1743 in Paris, France to a wealthy familyWent to college at des Quatre NationsStudied science and became a chemistPart of group that helped in the French RevolutionCaused beheading on May 8, 1794Things he demonstrated...With careful measurements, that transmutation of water to earth was not possibleAir is composed of 2 parts, one of which combines with metals to form calxesAir responsible for combustion was also the source of acidityInvented the system of chemical nomenclature still largely in use today including names such as sulfuric acid, sulfates and sulfitesLaw of Conservation of MassA few achievements of AntoineWon a gold medal on lighting the streets of Paris and designed a new method for preparing saltpeterStated the first version of the Law of Conservation of MassRecognized and named Oxygen and Hydrogen Changed chemistry from qualitative to quantitative scienceShowed nature is a closed systemHelped establish modern chemistryMade first modern chemical textbookDiscovered diamond was crystalline form of carbonSourcesInfohttp://cstl-csm.semo.edu/mcgowan/ch181/atomhist.htmhttp://scienceworld.wolfram.com/biography/Lavoisier.htmlhttp://www.westerncultureglobal.org/lavoisier.html
